Configure Cisco Router for DHCP Server

To configure Cisco Router for DHCP Server, we need to create the DHCP pool in the global configuration mode. The Cisco Switch DHCP configuration also covers the same steps.

In the process to configure DHCP on Cisco Router, you will need to configure the Cisco Switch that you added in the GNS3 program. Otherwise, the computers on the network will not be able to communicate with the Cisco Router. To configure the Cisco Switch, change the Cisco Switch settings as shown in the following image.

To configure Cisco Router for DHCP Server first run the Cisco Router in the GNS3 program. Then double-click on the Cisco Router to open the Console window and execute the following commands.

R1# conf t
R1(config)# interface fastethernet 0/0
R1(config-if)# ip address 192.168.8.1 255.255.255.0
R1(config-if)# no shutdown
